ACETYLENE-GAS GENERATOR.

SPECIFICATION forming part of Letters Patent No. 605,397, dated June 7,1898. Application filed July 20, 1897. Serial No. 645,293. (No morlel-lTo all whom it may concern.-

Be it known that I, JAMES H. COUPER, a citizen of the United States, anda residentof Baltimore city, State of Maryland, have invented certainnew and useful Improvements in Acetylene-Gas Generators, of which thefollowing is a specification.

My invention relates particularly to that class of generators in whichthe gas is developed by the action of water on calcium carbid. Incharging such generators it is important that no gas should escape whilethe carbid is being introduced and also that the generator may becharged while running without in any way interfering with its operation.

My invention consists in certain details of construction, which arefully explained in the following specification, reference being had tothe accompanying drawings.

Figure 1 shows a generator with my improvements attached. Figs. 2, 3, 4,5, 6, 7, 8, and 9 are detail views of a receptacle for calcium carbid orother material.

Referring to Fig. 1, 1 and 2 are gasometers.

3 and 4 are the movable parts of the same, which rise, and fall with thesupply of gas contained therein. 5 is a pipe connecting 1 and 2. 6 isavalve in pipe 5. 7,8, and 9 are rods for opening and closing valve 6.10 is the gas-delivery pipe. 11 is a safety-valve connectedto the pipe 5by means of a branch. 13 is an arm passing through the valve-stem, thelower end of the arm having a weighted roller 14 attached, the rollerhaving sufficient weight to'turn the valve and close it. Then the valveis closed, the upper arm 15 comes in contact with the side of thevalve-casing and the valve remains in a fixed position. 16 is areceptacle in which the calcium carbid is placed. 17 is a hand-wheel bymeans of which the bottom of the receptacle may be opened and thecontents precipitated into the gasometer 1. Both .the gasometers 1 and 2contain water to the levels shown by the dotted lines a z and w w. '12is a large gatevalve for cleaning out the gasometer 1. 41 is aperforated partition attached inside the movable part 3 of generator 1,as shown.

Referringto Figs. 2, 3, 4,5, and 6, the receptacle 16 and the manner inwhich it is attached to the part3 are shown. The top 18 is hinged at 19and clamped by means of the piece 20 and screw 21. 22 and 23 are flangesby means of which the receptacle 16 is fastened to the part 3. Thebottom 24 is clamped in position by means of the threaded rod 25,hand-wheel 17, and clamp 26, the operation of which will be explainedlater. 27 is a guide-piece which has two grooves 28 on its innersurface, through which the bottom 24 is moved back and forth. The clamp26 (a plan View of which is shown in Fig. .7) has two arms 29 29, whichextend into the grooves 28 28,'as shown in Figs. 3 and 6. Extendingdownwardfrom the undersurface of the bottom 24 are two pins 30 30.(Shown in detail in as the rod 25 is turned in one direction the nut isdrawn from right to left, pressing against the lower surface of thepiece 34,

which is pushed up,and the bottom 24 clamped against the receptacle 16.The bottom is kept from sliding endwise by means of the pins 30, whichextend into the holes 31 of the clamp 26. By turning the rod 25 in theop-= posite direction the nut 33 is moved from left to right away fromthe piece 34, and the bot tom 24 falls until it rests on the clamp 26,as shown in Figs. 5 and 6. To empty the contents of the receptacle, thebottom 24 is then drawn back by means of the rod 25 and hand- -wheel17.In Fig. 5 the bottom 24 is shown drawn from under the receptacle 16,thus permitting the contents to be emptied.

The operation of the machine is as follows:

In Fig. 1 the movable part 4 of the gasome-- ter 2 is shown at itshighest position, with the valve 6 closed and the part 3 of thegasometer 1 in a position midway between up and down. Suppose the gas isdrawn from gasometer 2 by way of the delivery-pipe 10. The part 4 willfall to a certain point, where the combination of rods 7, 8, and 9 willstart to open the valve 6, thereby admitting more gas from gasometer 1int-o gaso1neter2. The part 4 will rise again, and when it has reached acertain height the valve 6 will again close. In this way the supply ofgas in gasometer 2 is kept up. If it is desired to recharge the machinewith calcium carbid, the bottom of the receptacle 16 is tightly closedby means of the hand-wheel 17, as has been explained, the top 18removed, and a fresh supply of carbid placed in the receptacle. The top18 is then securely fastened and the contents emptied into the gasometerby means of operating the hand-wheel 17, as has been explained. 41,coming in contact with the water if the part 3 is sufficiently down. Gasis now generated by the action of the water on the carbid and the part 3will rise sufiiciently to raise the carbid out of the water and stop thegeneration of gas. If the generation of gas is too rapid, the part 3will rise and come in contact with the roller let, which will be raisedand the valve 11 opened by means of the lever 13. This, however, neveroccurs unless the partition should become broken and all the carbidprecipitated directly into the water. Valve 11 allows the gas to escapeand avoid any possibility of danger. To clean out gasometer 1 withoutinterfering with the supply of gas from gasometer 2, the valve isclosed, thereby severing the connection between 1 and 2. Valve 12 maynowbe opened and the contents of gasometer 1 removed.

Having now fully described myinvention, what I claim, and desire tosecure by Letters Patent, is-

1. The combination of a generating and a receiving gasometer, a pipeconnecting the gas-spaces of both, a valve in said pipe, operatingmechanism for the valve controlled by the movable part of thereceiving-gasometer, a receptacle mounted on the movable part of thegenerating-gasometer, the top of The carbid falls on the partition saidreceptacle opening outward and bottom inward, means for clamping the topin place, a hand-wheel and rod extending from the bottom to the exteriorof the gasometer, a nut operated by the rod said nut engaging with a lugon the bottom of the receptacle in such a way that when the rod isturned in one direction the nut engages with the lug and clamps thebottom, and when turned in the opposite direction unclamps the bottomwhich may then be drawn from under the receptacle by means of the rod, aperforated partition carried by the movable part of thegeneratinggasometer to receive calcium carbid' or other material fromthe receptacle, and a safetyvalve connected to the gas-space ofgenerating-gasometer and operated mechanically by the movable partthereof.

2. In a calcium-carbid receptacle having a removable-bottom, thecombination of a pair of parallel guides one on each side of thereceptacle at its lower edge, a yoke the ends of which rest in and slidein said guides, said yoke being provided with perforated lugs, athreaded rod passing through said lugs, and secured therein so as toturn but not move laterally, a nut upon said rod adapted to move in adirection parallel to the rod and having its upper surface beveled, andthe bottom resting upon and guided by the yoke, and provided with abeveled lug on its under side, which engages with the beveled surface ofthe nut; the whole yoke and bottom being moved back and forth by the rodin a direction par-- allel to it, and the bottom being clamped inposition by the nut, substantially as described.
